7 ASSEMBLY INSTRUCTIONS ASHFORD 4 & 8 SHAFT JACK LOOMS Tools required: Screwdriver, hammer, ruler, candlewax, light lubrication oil and adjustable spanner. Finishing the wood: The wood your Jack Loom is made of has been lacquered to provide a smooth attractive finish. If desired, use Ashford wax polish to enhance the natural beauty of the wood. Before Assembly: - Read the complete instructions and identify all parts and hardware. - BOLTS. Check and sort the sizes against the full-size drawing on page 3. Check quantities on page 4. - Rub candlewax or soap on the threads of the woodscrews to make assembly easier.
8 ASSEMBLY OF THE LOOM 1 Assemble the base as detailed in illustration 1 and 2 using 90 mm hex head bolts, washers and barrel nuts. Note the holes in rail BX are to the top. Bushes in parts C and CX are on the inside.
9 2 Bolt castle side E to the outside of base rail A, and the castle side EX to the base rail AX using 70 mm round head bolts, washers and hex nuts as shown in illustration 3. Note the nylon shaft guides are to the inside of the frame and holes for the beater stops face forward. 3 Secure the blocks O to the inside of the castle sides E and EX with 70 mm round head bolts, washers and nuts as shown in illustration 3.
10 4 Secure one rail M to blocks O using 40 mm screws. Illustration 4. Note the position of the holes for the steel rods x. 5 Place the 6 steel rods x into the rail M. 6 FOR FOUR SHAFT LOOMS: Place square wooden spacers onto the two lower rods x followed by a lever assembly N. Place two washers onto each lower rod x followed by another lever assembly N. Repeat this procedure until all the lever assemblies are in position, finishing with wooden spacers. A drop of light oil on the rods will help make treadling easier. See illustration 4a. FOR EIGHT SHAFT LOOMS: Place 5 washers onto the lower rods x followed by a lever assembly N. Place 2 washers onto each lower rod x followed by another lever assembly N. Repeat this procedure until all the lever assemblies are in position, finishing with 5 washers. A drop of light oil on the rods will help make treadling easier. See illustration 4a. 7 Locate the second rail M onto the steel rods x and secure to blocks O with 40 mm screws.

12 8 Identify the cloth beam supports F (left) and FX (right). FX has a counterbored hole facing the outside. 9 Attach but do not tighten FX to DX with an 80 mm hex bolt, washer and barrel nut and to EX with a 130 mm hex bolt washer and barrel nut as shown in illustration 5. Repeat for the opposite side with F, D and E. Keeping the nylon bushes to the inside. for eight shaft looms: A 195 mm threaded shaft, dome nut, washer and barrel nut n are used to connect F and FX to E and EX. 10 Slide the ratchet lever G onto the steel shaft on the cloth beam H and ensure the pawl engages the ratchet teeth. See illustration 6. 11 Twist the cloth beam support FX slightly and locate the cloth beam H into the nylon bush. Lower H so the holes in H and F line up and then tap a steel shaft p through the nylon bush and into H. Then tighten the bolts securing F and FX.
13 h 12 Secure the ratchet lever stop to the insde of the front upright DX with a 40 mm screw. The sloping side of the stop should face inwards at the top to support the lever. When transporting the loom pull the lever sideways past the stop and let it hang down. See illustration 7. 13 Attach the ratchet dog h to the right cloth beam support FX as shown in illustration 8 using a 50 mm hex bolt, oversize nut, washer and nyloc nut. The head of the bolt will have to be tapped into the counterbored hole. The dog should move freely after tightening the nut. See illustration 8. h
14 14 treadles four shaft looms: With holes in slots to the bottom, place six treadles J onto the long steel rod with round wooden spacers k between. Place a large hole washer at each end followed by the treadle blocks l. Note that the rod holes in l must be towards the top. Bolt both blocks l to BX with 70 mm round head bolts, washers and nuts as shown in illustration 9. treadles eight shaft looms: For the eight shaft loom an extra support block is bolted to the centre of BX and 5 treadles are located either side. 15 Tap a 50 mm hex bolt through the inside of castle side EX as shown in illustration 10 and secure to a spacer P with a washer and wingnut. Note the middle slot is closer to the rear of the loom and is used to hold the back beam in the closed position.
15 16 Attach the hole end of P to the back upright CX with a 55 mm round head bolt, washer and wingnut. 17 Remove the wooden spacer P from the castle E to allow the warp roller Z to fit between the uprights without twisting them. Then place the warp roller between the back uprights C and CX by locating the shaft of the warp roller into the nylon bush in CX. Secure the warp roller by tapping a steel shaft p through the nylon bush in C and into Z. Repeat steps 16 and 17 for the other side. 18 Thread two screw hooks into the brake lever W and one screw hook into the hole underneath FX as shown in illustration 12. 19 Push a 70 mm hex bolt and washer through the castle side EX. Place a washer, the brake lever W, a washer and then a nyloc nut onto the bolt. Tighten sufficiently with two spanners so the brake lever moves freely. See illustration 11. 20 Push the 55 mm round head bolt through the upright CX. Then locate a washer, brass bush, loop of the brake cable, washer and hex nut onto the bolt. Now wind the cable around the brake drum and attach the turnbuckle to the screw hook at the end of the brake lever W. See illustration 11. NOTE: When folding the loom the turnbuckle MUST be loosened. TURNBUCKLE
16 21 Locate the spring between the screw hooks in FX and brake lever W. See illustration 12. NOTE: If the brake does not easily release check the following: A) Adjust the turnbuckle so there is about 30 mm of sideways movement in wire rope. B) That the wire rope is wound evenly on the brake drum and is not crossed over. C) When the brake drum is manufactured and zinc plated, a rough finish can occur which may need to be smoothed off with either a fine file or emery paper. D) A drop of light lubrication oil on the brake drum may assist the brake to function properly. 22 Attach the handle f to the crank G with a 100 mm round head bolt by threading the bolt through f and G and locking it with a hex nut. Then locate crank G onto the shaft of warp roller Z and lock in place with a split pin e. Spread the ends of the pin to prevent it falling out. See illustration 12. NOTE: The cloth and warp roller must rotate in the direction shown. See illustration 12a. f Illustration 12a
17 23 assembly of the shafts Your Ashford Jack Loom has been supplied with Texsolv Heddles. Each bundle contains 100 heddles which enable you to use 200 per shaft on a four shaft loom and 100 per shaft on an eight shaft loom. To load the heddles: Take a bundle of heddles (DO NOT REMOVE THE PINK TIES) Thread the flat steel bars (see note at bottom of page if you have a 800mm loom) through the bundle top and bottom as illustrated in illustration 14b. Then carefully spring the steel bars into the slots in the shafts taking care not to bend the bars. THEN remove the ties and spread the heddles. Extra Texsolv heddles for finer threadings may be obtained from your Ashford dealer. The heddles can be used connected or cut. (Use sharp scissors.) Cutting is best when the heddles are hanging on the harness. PLEASE NOTE: If your loom is an 800mm loom, the steel bars are round and please omit step 24 and go straight to step 25.
18 24 Each shaft one hole on either side. Fit one hook v into one side of each shaft. Secure by pressing a dome cap w onto the hook. It may be easier to do this when the hook v is sitting across the corner of a table. Spread the heddles evenly either side of the hook and then clip the stainless steel bar over the hook. The hooks prevent the bars from sagging when being raised. See illustrations 13, 13 A and 14. 25 Rub candlewax on the ends of the shafts before loading them into the nylon guides. Load the shafts and locate the jack pin into the hole in the shaft. If any of the shafts are curved, load them so that the curves are all in the same direction. Load the harnesses so that if any are bent, to avoid them rubbing on each other put the bends all in the same direction
26 Attach the castle top rails T to the castle sides E and EX with 40 mm screws. Locate the shelf V onto the castle. It is easily removable for access to the shafts. See illustration 15. 27 Locate the front and back beams Y onto the tenons of uprights C, CX and D, DX. The beams are easily removable to allow access to the shafts when warping. 28 Tap the beater stops j into the castle sides E and EX. Note the lead holes for the screws face out. Then attach the rubber buffers to the stops with 16 mm screws. 29 Assemble the beater by joining the sides Q to the bottom rail R with 80 mm hex head bolts, washers and barrel nuts n. Note the shuttle race faces forward. See illustration 16. 30 Place the reed into the groove in the bottom rail R. Secure the top beater rail S to the sides with 75 mm round head bolts, washers and wing nuts. 19
20 j 31 Place the beater in position on the loom frame and push a 110 mm hex bolt and washer through the side Q, the front hole in the spacer blocks attached to the sides A and AX and secure with washer and nyloc nut. The two holes in the spacer blocks allow the beater to be moved forwards or backwards to suit the weaving. See illustration 17. Do not tighten bolts. Beater must move backwards and forwards freely.
21 32 Flame the ends of the nylon cords to prevent fraying. Then tie a knot in the cords and connect the treadles J to the parallel lams. See illustration 18. NOTE: There are four parallel lams and four slots in each treadle on the four shaft loom, and eight lams and eight slots in each treadle on the eight shaft loom. After determining the pattern required, connect the cord from each lam to the slot in the treadle directly beneath it. The knots in the cords locate into the holes in the underside of the treadles. Illustration 19 is one of many alternative tie ups for the four shaft loom with treadles one and six for tabby weave.
22 tie up for 8 shaft jack loom
23 33 Attach the raddle blocks to the castle sides E and EX with 40 mm screws. Then locate the raddle pins into these blocks and sit the raddle in position. See illustration 20. 34 Slide the round apron sticks into the pockets sewn into the end of the cloth aprons. Tie the round warp sticks parallel to the apron sticks with the cut pieces of string as shown in illustration 21. The loom is now ready to be warped.
